WB JEE 2021

MCQ (Single Correct Answer)

-0.25

Molecular velocities of two gases at the same temperature (T) are u₁ and u₂. Their masses are m₁ and m₂ respectively. Which of the following expressions is correct at temperature T?

$${{{m_1}} \over {u_1^2}} = {{{m_2}} \over {u_2^2}}$$

$${m_1}{u_1} = {m_2}{u_2}$$

$${{{m_1}} \over {{u_1}}} = {{{m_2}} \over {{u_2}}}$$

$${m_1}u_1^2 = {m_2}u_2^2$$
